Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the RPA display.
  2. Ignition ON, verify that a test lamp illuminates between the 12V voltage supply circuit terminal A and ground.
    • If the test lamp does not illuminate, test the voltage supply circuit terminal for a short to ground or an open/high resistance.
  3. Connect a test lamp between the control circuit and the 12V voltage supply circuit terminal A of the appropriate LED listed below:
    • Left amber LED control circuit terminal B
    • Center amber LED control circuit terminal C
    • Red LED control circuit terminal D
  4. Command the appropriate LED ON and OFF with a scan tool, verify that a test lamp turns ON and OFF when switching between commanded states.
    • If the test lamp does not illuminate, test the control circuit for a short to voltage or an open/high resistance. If the circuit tests normal, test or replace the object alarm module.
    • If the test lamp is always ON, test the control circuit for a short to ground. If the circuit tests normal, test or replace the object alarm module.
  5. If all circuits test normal, test or replace the RPA display.
